"This is one of my designs," Long Yi explained. "Originally, I planned to use this platform to make a tank. But due to power limitation, if crystal cores are used as power sources, they would need to be frequently replaced, and if Fighting Aura were to be used, it would require a Dragon Rider. Also, it wouldn't have any strategic significance. However, if this device were to be turned into a tractor, it would be a different story. Staying behind at the war front, it would not be an issue to comfortably replace crystal core power sources, and a charged crystal core could be reused. Moreover, it does not have heavy armor, so energy consumption is relatively low." He motioned at his sketch as he spoke.
Everyone was shocked by this outrageous idea. How come no one had thought about this before?
"But its production cost must be more expensive!" Morton, who had recovered from the shock, said.
